. SPECIFICATION forming part of Letters Patent No. 660,301, datedOctober 23, 1900.

Application filed June 1, 1899- To all whom it may concern.-

Be it known that 1, Lens J. LINDBEoK,a citizen of the United States,residing at Bishop Hill, in the county of Henry, State of Illinois, haveinvented certain new and useful Improvements in Mangles; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to mangles, and has for one object to provide adevice of this na-, ture which will be simple and cheap of.construction, easy and efflcient in its operation, and which, moreover,when not in use will have an ornamental appearance.

A further object of my invention is to provide a readily-operatedtension device for the rolls of the mangle and means for operating therolls. i

In the drawings forming a portion of this specification, and in whichlike letters of reference indicate similar parts in the several views,Figure 1 is a front view of my mangle when closed and showing theornamental appearance thereof. Fig. 2 is a front view of my mangle withthe front open and readyfor operation. Fig. 3 is a section on line 3 3of Fig. 2. Fig. 4 is a section on line 4 4 of Fig. 2. Fig. 5 is a detailsection taken through the shaft M and showing its cam and its yieldableconnection therewith.

Referring now to the drawings, in operating in accordance with myinvention I form a casing comprising a back a, sides I) and 0, top d,and bottom 6, the front comprising an upper hinged lid f, hinged to ahorizontal partition g in the casing and adapted to inclose amangle-compartment, there being a lower portion below said partitionhaving drawers h for any desired purpose.

It will be noted that the sides I) and c at their upper portions, whichare engaged by the lid f, are sloped backwardly from the bottom of thelid to the top of the casing, giving the casing when closed moreof theappearance of a desk.

Serial No. 719,029. (No modal.)

and a rearflange hisformed at the rear edgeof the plate, said front andrear flanges projecting in-the same direction with the upper and lowerflanges. The guide-plate c is similar to the guide-plate b and isseparated from the side cof the casing by an interspace t, as

shown.

Journaled in bearings formed in theplates bandc are the trunnions k andlof a roller m, which roller, has a sheet of fabric a secured thereto bymeans of tacks or other form of fastening means along one edge of, thesheet. This sheet is substantially thewidth of the roll and the securededge thereof lie longitudinally of the roller.

The trunnionlof the rollerm passes thlgough the plate 0 and into theinter-space t, within which interspace and upon said trunnion isarranged a pinion 0,-meshing with a second and larger pinion-p upon ashaft r, journaled in the side of the casing and having at its outer enda crank t, through the medium of which its shaft may be rotated torotate the roller m.

Slidably arranged between the upper and lower flanges of each plate I)and c is abearing-block B and C, respectively, which blocks are adaptedto move toward and away from the trunnions of the roller 0%. Each of thebearing-blocks has a downwardly and rearwardly directed bearing-slot D,which when the blocks are at the limit of their rearward movement are inalinement with the entering-ways f, permitting the insertion of thetrunnions- E and F of an adjustable roller 'H, adapted to be carriedtoward and away from the roller m as said bearing-blocksare'reciprocated, and thus exert pressure upon or release any bodyentered between the adjacent surfaces of the rollers.

In order to move the bearing-blocks forwardly, and therewith the rollerH, I arrange a cross-bar 1, whose ends project into the inin a similarmanner.

closure of the inwardlydirected flanges of the plates Z) and c andengage the bearingblocks, as shown in Fig. 3 of the drawings. A secondhorizontal partition L and a bar K are mounted between the partition 9and the top of the casing, and this bar K and the partition 9 havebearings in which is mounted an oscillatory shaft M, having an eccentricN fixed thereto or form ed integral therewith and adapted to engage thecross-bar I and press it forwardly as its shaft is rotated in onedirection and to release the cross-bar when its shaft is rotated in theopposite direction.

In order to oscillate the shaft M, I mount loosely thereon anoperating-lever O, connection being made between said lever and shaftthrough the medium of a spring-strap P, one end of which is connectedwith the lever and the other end of which is passed through adiam'etrical perforation in the shaft. Thus is formed a yieldableconnection between the shaft and its operating-lever, and as a result ayieldable pressure of the roller H against the roller m.

In order to hold the lever O in its adjusted positions to maintainpressure between the two rolls or .to hold them at any desired distanceapart, 1 form upon the bar K a notched segment R, adapted to be engagedby a projecting portion S upon the lever O.

The space above the partition L is divided to receive sliding drawersand also to form pigeonholes, as shown, or may be otherwise arranged, asmay be desired.

In the operation ofmy invention the fabric 'n is drawn outwardly fromthe roller 'm to lie upon the inner surface of the lid j", which isbrought to lie in a horizontal position, as shown in Figs. 2 and 3 ofthe drawings. The article to be mangled is then laid upon the cloth orfabric and the crank zfis operated, with the result that the roller 7%is rotated. At the same time the lever O is operated to move the rollerH forwardly and into engagement with the said fabric, exerting pressureupon said fabric and upon the material carried thereby. After thearticle has passed between the rollers the rotation of the rollers isreversed and the article removed from the fabric, folded, if desired,and again passed between the rollers When the operation is completed,the lever O is disengaged from its holding-segment and the roller Hallowed to return. This return may be assured or assisted by means ofhelical springs 'l and U, arranged between the forward edges of thebearing-blocks and stops V on the inner faces of the plates.

It will be readily understood that I may vary the specific constructionand arrangement herein shown and described, that I may use whatevermaterial may prove advisable for the different elements of my invention,and that I may equip the casing outside of the mangle-compartment asdesired without departing from the spirit of my invention.

Having thus described my invention, what I claim is- 1. A manglecomprising a roller mounted in stationary bearings, j on rnal-blocks, aroller mounted in the journal-blocks, said journalblocks being adaptedfor reciprocation to move the second roller toward and away from thefirst roller, a cross-bar engaged with the journal-blocks, a shaftadjacent to the crossbar, an eccentric upon the shaft and adapted toengage the crossbar to move it to shift the journal-blocks, alevermounted loosely on the shaft of the eccentric, and a spring having oneend connected with the lever and the other end connected with the shaftof the cocentric to form a yielding connection therewith.

2. A mangle comprising a roller mounte in stationary bearings,journal-blocks mounted for reciprocation with respect to the roller, asecond roller mounted in the journal-blocks, a cross-bar engaging saidblocks, a shaft journaled adjacent to the cross-bar, an eccentric uponthe shaft and adapted to engage the cross-bar to move thejournal-blocks, a lever mounted loosely on the said shaft, a springconnected at one end with the lever and at the opposite end with theshaft to form a yielding connection therebetween, and means forholdingthe lever at diiferent points of its movement.

In testimony whereof I affix my signature in presence of two witnesses.
